GNFZ Assessment Certificate
Global Network for Zero
Certify that buildings meet zero emissions and sustainability goals.
Key Strengths
- Incremental pathway allows buildings to start anywhere on the net zero journey
- Covers full Scope 1, 2, and 3 emissions — comprehensive GHG accounting
- Based on the industry-leading GHG Protocol framework
- Recognized by GRESB in its reporting process
- Aligned with SBTi targets and international ESG/green building regulations
- End-to-end support provided in creating a net zero plan
Ideal For
This certification is best suited for building owners, property managers, real estate developers, and facility managers seeking to document and reduce their existing buildings' Scope 1, 2, and 3 emissions. It is particularly valuable for organizations with ESG reporting obligations, SBTi targets, or GRESB participation requirements who need an incremental, structured pathway to net zero rather than an all-or-nothing approach.

Overview
The Global Network for Zero’s (GNFZ) certification for existing buildings focuses on elevating sustainability practices in architecture. This program aims to reduce carbon footprints and promote energy efficiency. Buildings are evaluated based on criteria like energy use, water management, and waste reduction. The certification history roots from a growing need for sustainable solutions, aligning with global climate goals.
GNFZ collaborates with key stakeholders, including governments, private sectors, and environmental organizations, to push for widespread adoption. Notable partners include major real estate developers and property management firms. Additionally, product manufacturers can also earn certification by meeting strict environmental standards.
In essence, GNFZ's initiative is a pragmatic step toward greener infrastructure, aiming to make measurable impacts in existing buildings across the globe.
Requirements & Verification
Evidence Requirements
Applicants must submit documentation to calculate Scope 1, 2, and 3 emissions for their building, including energy consumption data, utility records, and operational information. A net zero transition plan must be drafted with GNFZ's support. To maintain net zero certification, annual documentation must be submitted demonstrating ongoing compliance with net zero status.
Prerequisites
Assessment Process
The GNFZ certification process for existing buildings involves three stages: (1) an emissions assessment in which building data (Scope 1, 2, and 3) is submitted and reviewed to produce an emissions assessment certificate; (2) a net zero plan stage where GNFZ works with the building team to draft a transition roadmap, resulting in a net zero plan certificate; and (3) final net zero certification upon demonstrated achievement of net zero status, maintained through annual documentation submissions. GNFZ provides end-to-end support throughout the process.
Renewal & Compliance
Certified buildings must submit annual documentation to GNFZ to maintain their net zero certification status. This ongoing reporting ensures continued compliance with net zero emissions standards and supports the integrity of the certification.

Consider Alternatives If...
Avoid this certification if your building is newly constructed and better suited to a new-build net zero standard, or if your organization requires a widely recognized legacy credential (such as LEED or BREEAM) for regulatory compliance or tenant marketing purposes.
